Study Notes
Cell Organelles and Functions
- Cell Membrane: Allows certain molecules in and out of the cell.
- Chloroplast: Conducts photosynthesis.
- Nucleus: Stores DNA.
- Flagellum: Cell movement.
- Mitochondria: Powerhouse of the cell.
- Vacuole: Stores water.
- Endoplasmic Reticulum: Produces proteins.
- Golgi Apparatus: Processes and packages proteins and lipids.
- Rough ER: Synthesizes and processes proteins.
Protist Structure and Function
- Protists are eukaryotic organisms.
- Cytoplasm: Contains all the organelles inside the cell membrane.
- Cell Membrane: Forms the boundary of the cell.
- Chloroplast: Allows photosynthesis.
- Nucleus: Contains the genetic material of the cell.
- Flagellum / Pseudopod: Movement structures.
- Mitochondria: Responsible for cellular respiration, producing energy.
- Vacuole: Stores water or other substances.
- Golgi Apparatus: Processes and sorts proteins.
- Endoplasmic Reticulum: Involved in protein synthesis and transport.
- Ribosomes: Involved in protein synthesis.
Pathological Protozoans (Disease-causing organisms)
- Various protozoa can cause diseases such as:
- dysentery (amoebas in contaminated water)
- parasitic infections
- skin sores/ deep lesions (from bites)
- fever, weakness, and lethargy (insect bites)
- severe heart damage (kissing bugs)
- various types of infections, often spread through water, insect bites, contaminated food or contact
